one idea I have been seeing is that the game puts a restriction/bind on items a player has used, like armor and guns, the other is a total restriction on exotics, used or unused, so that players can't get an exotic from anyone but legendary and below can be traded as long as it HAS NOT been used. for example lets say the cryptarc and RNGesus give you a legendary armor for your arms. BUT you already have raid or exotic armor for your arms and see someone who is struggling to even get legendary armor you can put it up for trade, or for purchase, and set a reasonable amount for the armor. An example would be: 100 spin metal for the legendary crucible arm armor (i forgot the official name) or 100 spirit blooms for dark price Note: these were examples and I have no clue as to what a fair value would be for those weapons. But either way as long as the weapon or armor has not been used at all it could work. that way a player can't sell/trade a fully upgraded, or upgraded item in general, to someone who could use it. also prevents anyone from asking another player to upgrade armor for them so they don't have to do work and actually does something for players who could use the armor. But whatever its just a thought.
